Description

Technical Field

[0001] The present invention relates to the field of household appliances, and more specifically, to a housing assembly and a ceiling-mounted appliance having the same. This application claims priority to a patent application filed with the State Intellectual Property Office of China on July 26, 2024, with application number 202421803472.6 and titled "Housing Assembly and Ceiling-mounted Appliance Having the Same." Background Art

[0002] Common ceiling appliances include air conditioners, bathroom heaters, fresh air blowers, ventilation fans and other devices. The main body shell of existing ceiling appliances is restricted by the installation environment, and the size of the main body shell needs to match the size of the installation structure (for example, when installed on an integrated ceiling, it is necessary to remove the gusset plate and connect the main body shell to the keel above the gusset plate, then the size of the main body shell needs to be smaller than the size of the gusset plate. The width of the gusset plates on the market is mainly concentrated in 270mm, so the width of the main body shell is severely limited). This will limit the size of the volute duct structure in the main body shell, which will lead to a smaller impeller size for driving the airflow in the volute duct, affecting the air volume of the equipment.

[0003] For example, a bathroom heater is a common indoor heating device. Bathroom heaters include double-duct bathroom heaters, which allow airflow to circulate in two relatively independent flow channels and can construct different air supply channels, especially in models where one impeller corresponds to two independent volute ducts. Accordingly, this special model has higher requirements for air volume. In the traditional double-duct bathroom heater design, the size of the box is limited by the size of the ceiling gusset plate and the width of the keel, so that the size of the double-duct bathroom heater in the existing technology has been maximized. If the size of the main body shell is increased to increase the air volume, the volume of the bathroom heater shell will be too large to be installed on the ceiling. Without increasing the size of the main body shell to increase the air volume, the air intake can only be guaranteed by increasing the fan speed, but such a setting will significantly increase the noise during the operation of the appliance.

[0004] Currently, no effective solutions have been proposed for the above technical problems. Utility Model Content

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0034] Combine Figures 1 to 8 As shown, according to a specific embodiment of the present application, a housing assembly is provided.

[0035] Specifically, if Figure 1 、 Figure 5 As shown, the shell assembly includes: a main body shell 10, the main body shell 10 has at least two volute side panels 11, each volute side panel 11 is formed with at least part of the volute air duct 12, and at least one volute side panel 11 is provided with an opening; a spliced ​​volute 20, at least one spliced ​​volute 20, the spliced ​​volute 20 is connected to the main body shell 10, the spliced ​​volute 20 is arranged corresponding to the opening, the spliced ​​volute 20 has a blocking position, and the spliced ​​volute 20 has a position to be assembled; wherein, when the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 blocks at least part of the corresponding opening, and at least part of the spliced ​​volute 20 is located outside the main body shell 10, so that the spliced ​​volute 20 and the volute side panel 11 are surrounded by a volute enclosure.

[0036] By applying the technical solution of the present application, at least two volute side panels 11 are provided in the main housing 10, and each volute side panel 11 is formed with a volute air duct 12. By arranging the spliced ​​volute 20 corresponding to the opening, the volute side panels 11 and the spliced ​​volute 20 are enclosed to form a volute enclosure, which forms at least part of the fan structure. The spliced ​​volute 20 is used to expand the air duct capacity when in the blocked position, thereby eliminating the size restriction of the shell on the design of the fan part in the prior art, expanding the volute air duct capacity, and thus avoiding the defect in the prior art that the fan part is limited by the shell size and can only rely on increasing the fan speed to ensure the air intake. While ensuring the air intake, a higher speed is not required, thereby reducing the noise during the operation of the ceiling appliance. The ceiling appliance will have a higher air intake at the same fan speed. By adopting the technical solution of the present application, the problem of the inability to balance the air intake in the volute of the ceiling appliance and the operating noise of the ceiling appliance in the prior art can be solved.

[0037] The volute enclosure is formed by splicing the volute 20 and the volute side plate 11. It mainly plays the role of guiding the fluid movement and bearing the fluid impact. It serves as the side plate of the volute air duct 12 and forms the volute air duct 12 together with the volute air duct bottom plate. The volute enclosure can reduce noise and reduce fluid movement loss through reasonable shape design. The main body shell usually includes an air duct assembly, etc. The air duct assembly includes a volute air duct 12 formed by the volute and a main body air duct. The volute air duct 12 usually has an impeller. The main body air duct is used to guide the driven airflow in the volute air duct to the air outlet of the main body shell. The air outlet can be an air outlet connected to the indoor, an air outlet connected to the outdoor, or an air outlet connected to the indoor or outdoor respectively.

[0038] It should be noted that the main housing 10 and the volute side panels 11 can be integrally formed. In this structural form, the volute air duct 12 is formed by the volute side panels 11 and the main housing 10, and the main housing 10 serves as the side wall of the volute air duct in the height direction. The main housing 10 and the volute side panels 11 can also be two independently provided components, wherein the volute air duct 12 is formed by the volute side panels 11, and the volute side panels 11 are installed on the main housing 10. Those skilled in the art can make a reasonable choice based on various factors such as the product application scenario and product implementation process.

[0039] In an optional embodiment, when the spliced ​​volute 20 is connected to the main body housing 10, the spliced ​​volute 20 is located in a blocking position.

[0040] In another optional embodiment, when the main body housing 10 and the volute side plate 11 are relatively independently arranged, when the spliced ​​volute 20 is connected to at least one of the main body housing 10 and the volute side plate 11, the spliced ​​volute 20 is in a blocked position.

[0041] In another optional embodiment, the spliced ​​volute 20 is not connected to the main body shell 10 or the volute side panel 11. It is only necessary to maintain the spliced ​​volute 20 in a blocked position by other fixing methods. For example, when installing a bathroom heater on an integrated ceiling structure, it is first necessary to remove an integrated ceiling panel to form a mounting hole, then install the spliced ​​volute 20 on the keel on one side of the mounting hole, and finally push the main body shell 10 into the mezzanine space through the mounting hole. At this time, the spliced ​​volute 20 and the volute side panel 11 can also form a volute enclosure to achieve the extension and expansion of the volute air duct.

[0042] In another optional embodiment, when the spliced ​​volute 20 is removed from the main body housing 10 or not installed, the spliced ​​volute 20 is in the ready-to-assemble position, that is, the spliced ​​volute 20 is disconnected from the main body housing 10, and / or the spliced ​​volute 20 is disconnected from the volute side plate 11. Furthermore, when the spliced ​​volute 20 is in the ready-to-assemble position, it can also remain connected to the main body housing 10. For example, the spliced ​​volute 20 is constructed as a deformable structure connected to the main body housing 10, and by controlling the spliced ​​volute 20 to switch between different deformation positions, it can achieve its switching between the blocked position and the ready-to-assemble position.

[0043] Specifically, at least two volute side panels 11 are provided in the main housing 10, and a volute air duct 12 is formed on each volute side panel 11. An opening is provided on the volute side panel 11, and the spliced ​​volute 20 is arranged corresponding to the opening. The spliced ​​volute 20 is connected to the main housing 10, so that the spliced ​​volute 20, the volute side panels 11 and the volute air duct bottom plate are surrounded by a volute enclosure to form a complete volute air duct 12, which solves the limitations of the prior art on the volute air duct 12 and the size of the volute. Therefore, without changing the size of the ceiling panel and the keel width, the volute size is increased, and the spliced ​​volute 20 and the main housing 10 are assembled. While increasing the size of the fan and the volute, the implementation difficulty and cost are reduced.

[0044] Specifically, if Figure 3 、 Figure 5 、 Figure 6 As shown, further, at least two volute side plates 11 are provided with openings; there are at least two spliced ​​volutes 20, and at least two spliced ​​volutes 20 are provided in one-to-one correspondence with at least two openings, and each spliced ​​volute 20 has a blocking position and a position to be assembled.

[0045] Furthermore, the spliced ​​volute 20 is connected to the main engine housing 10, and the size of the volute enclosure after installation can be changed without affecting the installation size of the main engine housing, thereby changing the size of the fan after installation.

[0046] In an optional embodiment, when any of the spliced ​​volutes 20 is in the corresponding blocking position, the spliced ​​volute 20 blocks at least part of the corresponding opening, and at least part of the spliced ​​volute 20 is located outside the main body housing 10, so that the spliced ​​volute 20 and the corresponding volute side panel 11 form a volute enclosure. This arrangement expands the air duct and effectively increases the air intake.

[0047] When any spliced ​​volute 20 is located at the corresponding blocking position, the spliced ​​volute 20 will block at least part of the corresponding opening, including: the spliced ​​volute 20 can completely seal the corresponding opening, or the spliced ​​volute 20 can partially block the corresponding opening. Although there is a gap between the spliced ​​volute 20 and the opening, it can still complete the air guiding task.

[0048] The spliced ​​volute 20 blocks at least part of the opening, and the spliced ​​volute 20 is located outside the main body housing 10. This arrangement ensures that a sealed volute enclosure is formed between the spliced ​​volute 20 and the corresponding volute side panel 11, preventing debris or dust from entering the interior of the volute and affecting the normal operation of the equipment. At the same time, such a design can also effectively fix the spliced ​​volute 20, making it firmly connected to the main body housing 10, thereby improving the stability and durability of the equipment. Through the design of partially blocking the opening, it can be ensured that there is a certain gap between the volute enclosure and the volute side panel 11, avoiding the phenomenon of stagnation or blockage caused by wear or deformation, and compared with the completely sealed solution, it can still complete the air guiding task.

[0049] Specifically, when any of the spliced ​​volutes 20 is in the corresponding blocking position, the spliced ​​volute 20 and the corresponding volute side panel 11 are arranged to form a volute enclosure that is at least partially arc-shaped. The volute enclosure is intended to guide the airflow to flow smoothly in the volute, reducing airflow resistance and energy loss. Designing the volute enclosure to be at least partially arc-shaped can better adapt to the flow direction of the airflow, reduce the resistance of the airflow on the volute enclosure, and increase the flow rate of the gas in the volute air duct 12. In addition, the arc-shaped design of the volute enclosure can also reduce airflow turbulence and eddy currents, thereby reducing noise and vibration.

[0050] Specifically, if Figure 8 As shown, at least one partition 14 is provided in the main body housing 10. The partition 14 divides the internal space of the main body housing 10 into at least two cavities 15 along a first direction. The at least two cavities 15 are provided corresponding to the at least two volute side plates 11. Each volute side plate 11 is located in a corresponding cavity 15, so that each volute air duct 12 is formed in a corresponding cavity 15. The use of the partition 14 to divide the interior of the main body housing 10 into two chambers can distribute the airflow. The volute air duct 12 is formed in the corresponding cavity 15, which can better control the flow direction of the gas in the volute air duct 12.

[0051] It should be noted that the setting of the partition plate 14 does not affect the installation of the fan part 30 and the rotation of the centrifugal fan blade 32. In some embodiments, the output shaft of the motor 31 or the centrifugal fan blade 32 needs to pass through the partition plate 14.

[0052] Specifically, the first direction is the thickness direction of the main machine shell 10, which divides the main machine shell 10 into two cavities 15 (upper cavity and lower cavity).

[0053] In some embodiments, the first direction is the axial direction of the centrifugal fan blade 32.

[0054] In an optional embodiment, the first direction is the length direction or the width direction of the main machine shell 10. By the setting of the partition plate 14, the main machine shell 10 can be actually divided into multiple cavities 15 in different directions, thereby forming multiple independent volute air ducts. On the one hand, this facilitates the design and arrangement of the volute air ducts for different types of products. On the other hand, each volute air duct can have a corresponding spliced volute, thereby improving the overall air output of the equipment.

[0055] In an optional embodiment, the main machine shell 10 can be formed by multiple split parts, and there can be partition members between the split parts to achieve independent operation. For example, the multiple split parts each have a shell air duct for guiding air flow or an air outlet for discharging air flow, and partition members can be provided between these structures to achieve independent operation of the split parts. The partition members and the partition plate 14 can be provided integrally or relatively independently. The partition plate 14 can replace the partition members to achieve the partition function through reasonable profile design. Specifically, the main machine shell 10 has at least two air outlets 16, and the at least two air outlets 16 are provided in one-to-one correspondence with the at least two volute air ducts 12. Each air outlet 16 is in communication with the corresponding volute air duct 12. The provision of two different air ducts can increase the path of air flow, thereby improving the overall ventilation effect and making the air flow smoother.

[0056] In an optional embodiment, the air outlet 16 is two, and the two air outlets 16 are respectively provided on two side plates of the main machine shell 10 arranged opposite to each other, and / or the two air outlets 16 are respectively provided on two side plates of the main machine shell 10 arranged adjacent to each other and connected to each other, and / or the two air outlets 16 are respectively provided on the same side plate of the main machine shell 10. In this embodiment, the two air outlets 16 are provided on the two side plates of the main machine shell 10 arranged adjacent to each other and connected to each other, and the gas flow directions of the two air outlets 16 are different, which can disperse and release the heat of the gas, avoid local overheating phenomenon, and improve the heat dissipation effect.

[0057] Optionally, the two air outlets 16 can be configured as an air outlet of an indoor space and an air outlet communicating with an outdoor environment.

[0058] Specifically, there are at least two spliced ​​volutes 20. When the multiple spliced ​​volutes 20 are all located in corresponding blocking positions, at least two spliced ​​volutes 20 are respectively connected to both sides of the main body housing 10, or at least two spliced ​​volutes 20 are connected to the same side of the main body housing 10. Furthermore, at least two spliced ​​volutes 20 are respectively connected to two side panels of the main body housing 10, or at least two spliced ​​volutes 20 are connected to the same side panel of the main body housing 10.

[0059] In an optional embodiment, when each spliced ​​volute 20 is in its corresponding blocking position, the edge of the spliced ​​volute 20 smoothly transitions with the edge of the corresponding volute side panel. This ensures that the connection between the spliced ​​volute 20 and the opening does not generate excessive friction or resistance, allowing the spliced ​​volute 20 to be disassembled and assembled smoothly. Furthermore, the smooth transition design reduces the gap between the volute and the opening, preventing dust and other debris from entering the volute interior and protecting the internal mechanical structure of the volute from damage.

[0060] Optionally, when at least two spliced ​​volutes 20 are connected to the same side of the main body housing 10, the at least two spliced ​​volutes 20 are fixed as an integral structure. In other words, when the two spliced ​​volutes 20 are arranged on the same side of the main body housing 10, the two spliced ​​volutes 20 can form an integral structure. The two spliced ​​volutes 20 are fixed as an integral structure, which means that the two spliced ​​volutes 20 can be fixedly connected by a connecting structure (such as a buckle), or the two spliced ​​volutes 20 are arranged as an integral body.

[0061] Specifically, the housing assembly further includes a fan unit 30, which is provided in at least two portions. Both of the at least two fan units 30 are connected to the main housing 10. The at least two fan units 30 are provided in a one-to-one correspondence with the at least two volute air ducts 12, and each fan unit 30 is used to drive the airflow in the corresponding volute air duct 12. The two fan units 30 are provided in a one-to-one correspondence with the two volute air ducts 12, and the two fan units 30 are respectively located on the upper and lower sides of the partition 14. The upper and lower chambers operate independently, and the gas flows in the corresponding volute air ducts 12 without interfering with each other.

[0062] Specifically, the interior of the bathroom heater is designed with two layers of air ducts, each with its own inlet and outlet and a fan. This allows the two fans to be controlled independently to meet different ventilation needs. For example, this can decouple the ventilation and hot air functions, or enable independent control of hot and cool air. The two fan units 30 are respectively installed in the corresponding volute air ducts 12 through the base.

[0063] Specifically, in some embodiments, the housing assembly includes a fan unit 30, which is one fan unit 30, and the fan unit 30 is connected to the main housing 10. Providing one fan unit 30 can reduce the overall weight of the housing assembly. Specifically, the fan unit 30 includes: a motor 31, a fan blade structure, two volute air ducts 12 are adjacently arranged along the axial direction of the fan blade structure, and the two volute air ducts 12 are relatively independently arranged, and the fan blade structure is at least partially located in the two volute air ducts 12. The motor 31 is connected to the main housing 10. By connecting the motor 31 to the main housing 10, it can be ensured that the motor operates stably during operation and the position of the motor 31 is fixed.

[0064] In an optional embodiment, a single fan unit 30 includes a blade structure connected to a motor 31. A through hole is provided between the two volute air ducts 12, and the blade structure is inserted into the through hole. This allows different parts of the blade structure to be located in different volute air ducts 12, thereby enabling a single motor 31 and a single blade structure to simultaneously drive airflow in different volute air ducts 12. The technical solution of this embodiment reduces product cost and weight, improves product integration, and thereby enhances product competitiveness.

[0065] Furthermore, in some embodiments, the fan blade structure includes two groups of centrifugal fan blades 32, both groups of centrifugal fan blades 32 are connected to the output shaft of the motor 31, and the two groups of centrifugal fan blades 32 are arranged corresponding to the two volute air ducts 12. Each centrifugal fan blade 32 is located in the corresponding volute air duct 12, so that the centrifugal fan blades 32 drive the air flow movement in the corresponding volute air duct 12.

[0066] Specifically, each group of centrifugal blades 32 includes a plurality of blades spaced circumferentially, and each of the plurality of blades has a wind-gathering surface formed on its surface. The wind-gathering surfaces of the blades of one group of centrifugal blades 32 rotate clockwise, while the wind-gathering surfaces of the blades of the other group of centrifugal blades 32 rotate counterclockwise. The wind-gathering surfaces formed on the surfaces of the centrifugal blades 32 allow air to flow more smoothly through the blades, reducing resistance and increasing the propulsion force and wind speed of the centrifugal blades 32. The wind-gathering surfaces of the blades of one group of centrifugal blades 32 rotate clockwise, while the wind-gathering surfaces of the blades of the other group of centrifugal blades 32 rotate counterclockwise. The two opposite rotations of the wind-gathering surfaces cause the air entering the fan unit 30 to flow in two different directions under the rotation of the centrifugal blades 32, and to flow out from the two air outlets 16 connected to the two volute air ducts 12.

[0067] In an optional embodiment, the fan unit 30 includes a blade structure. The blade structure can be configured in a structure different from a centrifugal blade, for example, the blade structure can be configured as a mixed flow blade or an axial flow blade. Furthermore, the fan unit 30 can also be configured in the form of a bladeless fan, which is driven by a compressor and pressurized to achieve airflow movement in the volute air duct 12.

[0068] Specifically, the two sets of centrifugal blades 32 are configured to have the same diameter, and / or the two sets of centrifugal blades 32 are configured to have different diameters. In this embodiment, the two sets of centrifugal blades 32 are configured to have the same diameter, ensuring that the two sets of centrifugal blades 32 are subjected to the same force when the motor 31 rotates. By maintaining the same diameter of the centrifugal blades 32, the rotation of the centrifugal blades 32 can ensure that the flow rate of gas in the two cavities 15 is the same. The centrifugal blades 32 will be subjected to similar airflow and blade loads during rotation, thereby maintaining balance and avoiding vibration or loud noise caused by uneven force due to different diameters.

[0069] Furthermore, the two volute air ducts 12 are adjacently arranged along the axial direction of the fan blade structure, and the two volute air ducts 12 are relatively independently arranged. The technical solution of this embodiment realizes the partitioned arrangement of multiple air ducts of the housing assembly. On the one hand, different volute air ducts 12 can be used to perform different functions of the ceiling appliance (for example, two volute air ducts 12 can respectively perform ventilation and heating). On the other hand, volute air ducts 12 in different positions can be used to match structures such as air outlets in different positions.

[0070] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0071] 1. This solution increases the size of the volute and improves the air supply performance by adding a spliced ​​volute and surrounding the spliced ​​volute and the volute side panels to form a volute enclosure without changing the overall installation size of the shell.

[0072] 2. When installing this solution, first insert the spliced ​​volute and shell into the installation position respectively, and then detachably connect the spliced ​​volute and shell to form a complete air duct. The spliced ​​assembly method greatly reduces the implementation difficulty and cost.

[0073] According to another specific embodiment of the present invention, a ceiling-mounted appliance is provided, which includes a housing assembly, which is the housing assembly in the above embodiment. The ceiling-mounted appliance includes an air conditioner, a ventilation fan, a range hood, a bathroom heater, an exhaust fan, etc.

[0074] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
